Additive and subtractive prosumer digital fabrication with RepRap 3D printer

Open-source RepRap 3-D printers have made distributed manufacturing and prototyping an affordable reality. This paper presents novel modifications to a RepRap design that increase RepRap capabilities well beyond just fused filament fabrication. The design is a significantly modified derivative of the Rostock delta-style RepRap 3-D printer. Modifications were made that permit easy and rapid repurposing of the platform for milling, paste extrusion and several other applications. All of the designs are open-source and freely available.In addition to producing fused filament parts, the platform successfully produced milled printed circuit boards, milled plastic objects, objects made with paste extrudates such as silicone, food stuffs and ceramics, pen plotted works and cut vinyl products. The multi-purpose tool saved 90-97% of the capital costs of functionally equivalent dedicated tools.
